Discussion | Erythranthe inconspicua occurs in Sierran counties from Kern north to El Dorado and then is apparently disjunct further northward to Butte County. A record from Los Angeles County (Bigelow s.n., 14 May 1854, the type of the species) is probably mislabeled, as other collections by Bigelow on the same day are from Calaveras County.

In addition to the features noted in the key and descriptions, the fruiting calyces of Erythranthe grayi are distinctly more inflated than those of E. acutidens and E. inconspicua. G. L. Nesom (2012g) maintained E. grayi as distinct from E. acutidens, relying primarily on fruiting pedicel length (see key above), but the two have nearly identical ranges (Tuolumne County south to Kern County), and study of additional collections suggests that only a single species may be represented.
